EJECTOR MECHANISM For: FIREARMS.

SPEGIFIIOATION forming part of Letters Patent No. 715,903, datedDecember 16, 1902.

Application filed April 25, 1901. Serial No. 57,364. (lilo model-l I.The present invention relates to extractor and ejector mechanism'forguns of the breakdown type, and is shownas embodied in a single-barreledshotgun. The object of the invention is to simplify I5 the ejectormechanism, so as to obtain a device which will operate satisfactorilywithoutmaterially increasing the expense of construction.

In accordance with the invention the extractor, which cooperates withtheflange of the shell in the usual way, is mounted in a suitable guidein the barrel-lug'and is provided with aspring, the tendencyof which isto move the extractor in such a direction as to force the shell out ofthe chamber. The said extractor is normally held in place against thestress of the said spring by means of a catch which is arranged to beoperated upon by a catch-actuator'or tripping device in 20 response tothe movement of the barrel with relation to the frame when the gun is.broken down or opened. Both the catch and the tripping device aremovably mounted in a recess in the barrel-lug below the extractor-guideiIn accordance with the invention the frame is provided-with an undercutrecess for the barrel-1ug,.the shoulders at the top of the said recesscooperating with the tripping device to release the ejector when thebarrelhas- 40 been tipped down far enough to permit the shell to clearthe'breech-block.

The tripping device is shown as pivotally mounted, and the pivot-pin isarranged to ex tend laterally beyond the barrel-lug and constitutes astop to prevent the barrel from being tipped beyond a certain point, theengaging portion of said tripping device being so related to the saidpivot that it will be acted upon just before the said pivot is stopped,thus releasing the ejector. vThis stop prevents any further movement ofthe tripping device, so thatthe movement of the catch is limited, andthe said catch may be arranged to cooperate with a second engagingportion of theejector to limit the movement thereof-.55, and hold thesame against the stress of the spring after the ejector action. e

Figure 1 is a longitudinal section of a device embodying the-invention,the gun being.

The extractorrod a, which is also utilized as an ejector, is mountedin-a guide-bore?) in the barrel-lug B and is acted upon by a suitablespring b herein shown as a spiral. spring, interposed between the end ofthe ex- I tractor-rod and the endof the guide-passage. 7c

The said.ex tractor-rod is held-against the stress of said spring bymeans of a catch c'in such a position that the shell-engaging portion awill not act to any material extent upon the shell, the spring I) thusbeing kept under tension, and the said catch cis nibv- "f ably mountedin thebarrel-lug and normally stands in the path of a shoulder a formedon the under-side of the extractor-rod a. As indicated in Figs. 1 and 2,the said catchfc '80 consists of a vertically movable plunger mounted ina guide here or opening B in the barrel-lug and capable of being movedtoward and from the extractor, so as to engage or disengage the shouldera The said catch is arranged to be acted upon by a tripping device d,which is pivotally supported in the barrel-lug, the pivotal supportbeing shown as afl'forded by a transverse pin d, which extendscompletely through the barrel-lug and .jgo

sides. In the construction shown in Figs. 1 and 2 the said trippingdevice has a projection 01 which epters a suitable recess'in the plungerc, and the tripping device (1 is also acted upon by means of a spring (1the tendency of which is to rock the tripping device upon its pivot insuch a direction as to force the catch 0 toward the extractor-rod a..With

the parts in normal position, therefore, the .to full action of thespring I) upon'the extrac tor-rod is prevented by the said catch 0,which is in the path of the shoulder a w i To get the proper'e3ectoraction, it is nee-- This may be accomplished, as herein shown,

To perform this operation, the tripping device d is shownas provided with tripping projections (Z which extend laterally beyondthe sides of the barrellug, and the frame A of the gun is provided withan undercut recess A-, the projecting shoulders A of which overlie thetripping projections (Z so to engage the same when the gun is brokendown and the lug moved upward in the recess.

The catch 0 normallystands far enough in front of the shoulder a to admit of such slightmovement, the ejector member being held, of course, when the gun isclosed by engagement with the breech-block.

The catch may obviously be supported in the barrel-lug in any suitableWay,'a modification being shown in Fig. 4 in which the catch cispivotally supported upon a pin 0 which extends transversely through thelug, the action being the same as in the construction already described.

I claim 1. Extractor and ejector mechanism comprising an extractorlongitudinally movable in the barrei-lug and provided with a spring;

. a catch movably supported in the barrel-lug below said extractor andadapted to hold the same against the stress of its spring; a trippingdevice independent of but cooperating with said catch, said trippingdevice also beingmovably supported in the barrel-lug; and an undercutrecess in the frame, the upper surfaces or shoulders of which areadapted to codperate with a projecting portion of the said trippingdevice when the barrel is tipped, as set forth.

2. The combination with the frame provided with an undercut recess forthe barreldug; of an ejector mounted in the barrel-lugand provided witha spring; a catch for said ejector also mounted in the barrel-lug;atripping de vice for said catch mounted on a transverse pivot'pin insaid lug, the ends of the said pin projecting beyond the sides of thesaid lug to cooperate with the upper or overlying surface of theundercut recess in the frame and afford a stop for the barrel; and aprojection of said tripping device also projecting beyond the side ofthe barrel-lug to engage the upper surface of said recess before it isengaged by the pivot-pin, substantially as described.

3. The combination with the ejector pro vided with a spring; of a catchfor said ejector consisting of a plunger mounted in a suitable bore inthe barrel-lug and cooperating with a shoulder on the ejector; atripping device pivotally sn pported in said barrel-lug and cooperatingWith said catch; and an undercut recess in the frame, the upper oroverlying surface of which cooperates with the tripping device torelease the ejector, substantially as described. i

.4. The combination with the ejector provided with a spring; or" a catchforsaid ejector to hold the same in position against the stress of saidspring; stripping device forsaid catch mounted in the barreldug andhaving a projection underlying the upper surface or overlying portion ofan undercut recess in the frame; and a portion of said tripping deviceto engage and positively actuate said ejector prior to the tripping ofthe catch, substantially as described.

In testimony. whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
